Problems solved by technology

The disadvantage of this type of elastic fiber application is: it cannot be used as bare silk, and it must be covered with other fibers as a core yarn to have practical value; it needs special core yarn equipment to process, and the processing process is long and the elasticity is difficult to control Uniform; at the same time, this type of elastic fabric has the disadvantages of easy relaxation and poor chemical stability when used repeatedly

Embodiment 1

[0031] Five pieces of two-flying satin, the preparation steps are as follows:

[0032] 1) Preparation of composite polyester filament: Polyethylene terephthalate (PET) and polytrimethylene terephthalate (PTT) are used in a composite ratio of 60 / 40 to obtain a fineness of 65D through composite spinning technology Composite white silk; or add PET-based masterbatch and PTT-based masterbatch respectively in the spinning process to obtain the same fineness range, dope-colored composite yarn;

[0033] 2) Weft yarn forming method: the composite white silk in step 1) or the composite silk dyed by the stock solution and the 90Nm / 2 wool / polyester 70 / 30 blended spun yarn of 790Z twist / m are paralleled on the doubling machine and twisted Obtain a doubling yarn with a twist of 1000S twist / m; control the doubling tension of the wool yarn to 4.82g, and the doubling tension of the filament to 2.32g, so that the composite white silk or the composite silk is in a state of straightening and not ...

Abstract

The present invention relates to a polyester composite filament parallel-thread type latitudinal elastic wool fabric and its preparing method. The fabric is characterized in that composite yarns formed by paralleling threads of PET and PTT polyester composite filaments and wool or wool blended fine yarns are used as the latitudinal yarns; the PET and PTT polyester composite filaments are dope-dyed or white self-curly; the wool fabric has 5-40 percent tensile elasticity in the latitudinal direction. The fabric has the advantages of stable and durable elasticity, strong wool feeling as well as simple and convenient processing.

Description

technical field [0001] The invention relates to a latitudinal elastic wool fabric with 5-40% tensile elasticity using white or dope-colored polyester composite filament as weft yarn and a preparation method thereof, belonging to the field of new textile materials. Background technique [0002] Existing woolen weft elastic fabrics are generally realized by adopting wool (or wool blended) yarns to cover elastic fibers such as spandex (such as Lycra), polyolefins (such as XLA fiber of DOW company) to form core-spun yarns. The disadvantage of this type of elastic fiber application is: it cannot be used as bare silk, and it must be covered with other fibers as a core yarn to have practical value; it needs special core yarn equipment to process, and the processing process is long and the elasticity is difficult to control Uniform; at the same time, this type of elastic fabric has the disadvantages of easy relaxation and poor chemical stability when it is used repeatedly.
